UK ETA and Dual Nationality: When You Still Need to Apply in 2026

Travelling with two passports? Here’s the crucial rule: you only need a UK ETA if you’re entering the UK with a non-British or non-Irish passport that qualifies for visa-waiver entry. If you hold both a British and Irish passport, you do NOT require an ETA—nor will you need one when you travel on your British or Irish document. This means ETA dual nationality situations mostly apply to third-country combinations: for example, American–Brazilian, Canadian–Italian, Australian–British, or Japanese–Korean passport holders. Yet edge cases abound. What if your British passport has expired? What if you’re eligible for British citizenship by descent but haven’t applied yet? This guide unpacks the rules, edge cases, and practical steps for dual citizens planning UK travel in 2026.

Understanding the Dual Nationality Rule: British and Irish Passports

The central principle is straightforward: British citizens and Irish citizens have automatic right of entry to the UK without any travel authorisation. Therefore, if you hold a British passport, an Irish passport, or both, you are exempt from the UK ETA requirement entirely. This exemption applies regardless of your second, third, or fourth nationality. The UK recognises the Common Travel Area agreement with Ireland, which grants Irish citizens the same freedom of movement as British citizens. Consequently, any traveller with a valid British or Irish passport should use that document for UK entry and ignore ETA applications altogether. However, the practical question emerges: which passport should you actually travel with? The answer depends on your individual circumstances, visa requirements for onward travel, and document validity dates.

If Your British Passport Is Expired or Not Yet Issued

A frequently overlooked scenario: you hold British citizenship by descent or recent naturalisation, but your British passport either expired or hasn’t been issued yet. In this interim period, you cannot use a non-existent or invalid British document to enter the UK. If you hold a second passport from a visa-waiver-eligible country (such as the United States, Canada, or Australia), you must apply for a UK ETA using that passport. Once your new British passport arrives, you can discard the ETA and travel on your British document instead. This is a temporary measure, not a permanent requirement. Conversely, if your second passport requires a visa for UK entry, you’ll need to apply for a UK Standard Visitor Visa instead. The timeline matters: if your British passport application is pending and will arrive before your trip, wait for it rather than incurring ETA fees.

Dual Nationals: Both Passports Visa-Waiver Eligible

Many dual nationals hold two passports that both qualify for visa-waiver entry to the UK. Examples include US–Canadian, US–Australian, Canadian–Australian, or Japanese–South Korean combinations. In these situations, technically neither passport requires an ETA when used alone—but this is where ETA dual nationality considerations become relevant. You are not obligated to apply for either ETA. However, from a practical travel perspective, you might choose to apply for an ETA under one passport to streamline border procedures and create a documented record of entry permission. If you apply, use the passport you’re most likely to travel on, as the ETA ties to a specific passport number. Applying for ETAs under both passports is unnecessary and wastes money; one is sufficient.

Mixed Scenarios: One Visa-Waiver, One Visa-Required Passport

Complications arise when you hold one visa-waiver-eligible passport and one that normally requires a UK visa. For instance, you might be a US–Indian dual national, or Canadian–Brazilian. If you travel on your US or Canadian passport, you only need an ETA (cost £20 in 2026). If you travel on your Indian or Brazilian passport, you’ll need a Standard Visitor Visa instead, which requires more documentation, takes longer to process, and may cost more. The practical recommendation: use your visa-waiver passport and apply for the ETA. This is faster, cheaper, and involves less bureaucracy than obtaining a Standard Visitor Visa. However, if your visa-waiver passport is expiring soon and your visa-required passport is new, you might choose to apply for the visa using the other document—plan ahead when possible.

Commonwealth and Non-Commonwealth Dual Citizens

A subtle distinction: many Commonwealth nationals benefit from visa-waiver eligibility, but not all. Australian, Canadian, New Zealand, and South African citizens generally qualify for UK visa-waiver entry and thus need only an ETA. However, if you hold dual citizenship with a non-Commonwealth country whose nationals require a UK visa (such as India, China, or Russia), you must use the Commonwealth passport for visa-waiver entry or apply for a full visa using the other document. Some dual nationals hold two Commonwealth passports (e.g., Australian–New Zealand or Canadian–Australian), in which case both are visa-waiver eligible and neither requires an ETA. Check the UK Home Office’s current visa-waiver country list, as eligibility occasionally changes. Additionally, some Commonwealth nations have unique arrangements: for example, Hong Kong BN(O) passport holders historically had different requirements, though as of 2026 they follow standard visa-waiver rules if the passport is valid.

Special Cases: Chagossian and Citizenship by Descent

Two edge cases deserve specific attention. First, Chagossian citizens and stateless individuals claiming UK citizenship have limited travel options and may not qualify for standard visa-waiver entry. If you hold Chagossian citizenship or believe you might, contact the UK Home Office directly before attempting an ETA application, as your case likely requires individual assessment. Second, citizenship by descent (common among those born abroad to British parents) grants full British citizenship rights, but the process of obtaining your British passport can take months. During that waiting period, if you hold another visa-waiver-eligible passport, apply for an ETA using that document. Once your British passport is issued and arrives, your ETA becomes unnecessary. Conversely, if your second passport requires a visa, you’ll need to apply for a Standard Visitor Visa while your British passport application is pending—though many prefer to wait for the British passport to avoid visa fees and application complexity.

How to Apply for an ETA as a Dual National

When you have determined that an ETA is needed, the application process is identical regardless of dual nationality status. You apply for the ETA using whichever passport you’ll travel on. During the online application, you’ll enter your passport number, issue date, expiry date, and personal details. The system does not ask about second passports or multiple nationalities; it only processes the single document you’ve selected. Crucially, once your ETA is approved, it is tied to that specific passport number. If you later decide to travel on your second passport instead, your first ETA becomes irrelevant—you’ll need a new ETA under the second passport’s number. This is why it’s important to choose your travel passport in advance and stick with it throughout your journey. The ETA costs £20 (as of April 2026), is valid for two years, and permits multiple entries to the UK.

Practical Tips and Common Pitfalls

Here are key lessons for dual nationals planning UK trips. First, always carry both valid passports when travelling, even if you only intend to use one for UK entry. Customs officers may ask to inspect both documents, particularly if they notice evidence of dual nationality on your entry card or baggage. Second, never assume you need an ETA; verify your passport’s status on the UK Home Office website before spending time or money on an application. Third, keep your ETA approval confirmation and passport in easily accessible locations during travel, as you may be asked to show proof of authorisation at the border. Fourth, if your travel plans change and you want to switch to your second passport, check whether an ETA (or visa) is needed for that document before assuming you can simply use it at the gate. Finally, do not attempt to apply for ETAs under both passports simultaneously or use false information to obtain multiple authorisations—border officials have access to comprehensive databases and fraudulent applications can result in entry denial and further immigration complications.

Često postavljana pitanja

Do I need an ETA if I hold both British and another passport?

No. British passports grant automatic right of entry to the UK. You do not need an ETA, visa, or any other travel authorisation. Simply travel on your British passport and you’re cleared for entry.

My British passport hasn't arrived yet. What if I'm travelling soon?

If your second passport is from a visa-waiver-eligible country, apply for an ETA using that passport. Once your British passport arrives, you can discard the ETA. If your second passport requires a visa, apply for a Standard Visitor Visa instead.

I hold US and Canadian passports. Do I need an ETA?

Neither passport requires an ETA for UK entry, as both are visa-waiver eligible. You do not need to apply for anything unless you wish to do so for administrative clarity (optional).

Which passport should I use: my visa-waiver or my visa-required one?

Always use your visa-waiver-eligible passport if you have one. This avoids the complexity, cost, and delay of a full visa application. Only use your visa-required passport if your visa-waiver passport has expired or is invalid.

Can I apply for an ETA under both of my passports?

Technically yes, but it’s unnecessary and wasteful. An ETA is tied to a specific passport number, so you only need one under whichever passport you’ll actually travel on. Applying for both doubles your costs with no benefit.

What if I'm a Chagossian citizen or claim citizenship by descent?

Chagossian citizens should contact the UK Home Office directly before applying, as your case may require special handling. For citizenship by descent, apply for your British passport as soon as possible; while you wait, use a second visa-waiver-eligible passport with an ETA if needed.

Will border officers know I hold two passports?

Possibly, depending on stamps and entry records in your documents. Always carry both valid passports when travelling internationally, as officers may inspect them. Do not attempt to conceal your dual nationality, as this can create serious complications at the border.
